H ERBERT WEINER ATTORNEYS 3,025, 69.? Patented Mar. 13, 19%2 3,025,092 PUSH BUTTON WINDOW GUARD Herbert Weiner, 763 Ocean Parkway, Brooklyn 30, NY. Filed Apr. 20, 1960, Ser. No. 23,499 4 Claims. (Cl. 292163) This invention relates to improvements in locking devices and, more specifically, to a new and improved safety window guard designed for a more satisfactory interlocking of any objects which are shiftably arranged, as for instance sliding doors, sliding windows, vehicle doors and windows, elevator doors, cage closures, gates, shutters, and the like.

An object of the present invention is the provision of a device of the character described which will safely keep the objects in the position in which they are interlocked and which cannot be unlocked inadvertently nor can it be unlocked from the outer side of a room or the like for the locking of the windows or doors of which my guards are employed.

Another object of the present invention is the provision of a device of the character described which can be attached easily to any existing windows, doors and the like without removing such windows, doors and the like from the structure, vehicle, etc. to which they are alfixed.

Yet still another object of the present invention is the provision of a device of the character described which is light in weight, simple in construction and inexpensive to manufacture, but which also is sturdy and well adapted to withstand the rough usage to which such devices are ordinarily subjected.

A further object of the present invention is the provision of a device of the character described which automatically, and without turning any latch or the like, locks and guards a window whenever one sash is brought into a predetermined position relative to the other sash, so that there will be no danger of forgetting to lock a window or the like when closing the same.

With the foregoing and other objects which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangements of parts of the embodiment disclosed Without departing from the spirit of the invention as claimed.

In the accompanying drawing I have set forth an illustrative embodiment of my' invention.

In said drawing:

FIGURE 1 is a perspective view of a preferred embodiment of my invention as it appears when seen from the inner side of a closed double-sash sliding window;

FIG. 2 is a vertical sectional view through the center of FIG. 1;

FIG. 3 is a sectional view like FIG. 2, but showing the window partially open;

FIG. 4 is a front plan view of the embodiment of FIGS. 1 and 2 as it appears when it is detached from the window;

FIG. 5 is a partial side view and sectional view on the line 55 of FIG. 4;

FIG. 6 is an enlarged sectional view on the line 66 of FIG. 4; and,

FIG. 7 is a front plan view of a modification.

Similar reference characters refer to similar parts throughout the several views.

While my device can be used in connection with a great variety of shiftable objects, it is shown in the drawing as applied only to a window which has a lower inner window sash or frame 2 and an upper outer window sash or frame 3. The frames 2 and 3, which hold the window panes 1 and 5, and which form no part of my rim section 23 (FIGS. 5

present invention, are up and down shiftable in a wellknown manner and are shown in FIGS. 1 and 2 of the drawing in closed position. My improved locking device consists primarily of a flange member 7, an intermediate telescopic member 10, a cup-shaped hollow button member 11, a spring 12, and a clip member 15. The flange member 7 has a base portion 17 provided with holes 20, through which are extended screws 21 or the like (FIG. 1), for securing the device to an upper window sash or frame 3. A hollow portion 22 is extended from one side of the base portion 17, and has an inwardly extended and 6). The member 10 has a hollow main portion 24, one end of which is provided with an inwardly extended rim portion 25, while its other end is provided with an outwardly extended rim portion 27, which is slidable in the hollow portion 22 of the element 7 and is adapted for engaging the rim section 23 of the element 7. I prefer to provide the member 10 also with inwardly extending sections or prongs 30 (FIGS. 5 and 6) opposite the rim portion 27 and in spaced relation to the rim portion 25. The button 11 has a hollow, cup-shaped main portion 31 and an outwardly extended rim portion 32, which is slidable in the main portion 24 of the member 10 and is adapted for engaging the rim portion 25 of the member 10. The clip member 15 is substantially of a U-shaped formation and has inwardly toward each other directed extremities 33, which engage outer sections of the portion 22 near the rim section 23 of the member 7. The elements 7, 10, 11 and 15 can be made of plastic material or of metal or the like, and the elements 10 and 11 are slidable telescoped into each other as well as into the flange member 7. Any suitable resilient means, for instance a coiled spring 12 is interposed between the inner side of the knob 11 and the clip 15, so as to force the elements 10 and 11 into an extended position as shown in FIGS. 1, 2, 5 and 6. One or more of my new and improved window guards may be attached to either side of window at different heights. This will permit a window to be guarded when it is open to allow for fresh air. In the instance shown in. FIGS. 1, 2 and 3 a guard is mounted on the lower portion of an upper sash 3, and a striking plate 40 is secured to a top portion of the lower sash 2 by means of screws 41 or the like. If the window is closed, the main portion 24 of the member it rests against the plate 40, as: may be seen in FIGS. 1 and 2, so that the window cannot be opened until one has pressed upon the button 11, so as to force the same into the member 10, thereby the rim section 32 engaging the prongs 3i) and forcing the member 10 into the tubular portion 22 of the member 7.. When this is accomplished the elements 10 and 11 are in the position shown in FIG. 3, so that they no longer extend beyond the member 7 upon the plate 40, thus allowing the sashes 2 and 3 to be moved relatively to one another, so as to open the window. When the window is closed, the spring 12 will force the elements 10 and 11 out of the member 7, so that they again will resume the position of FIGS. 1 and 2, thus safely locking the window.

While the elements 10 and 11 as well as the portion 22 of the member 7 have been shown as being circular in FIGS. 1 to 6 inclusive, it will be obvious that they also can be of any other shape. For instance, they can be rectangular as shown in FIG. 7, where a flange member 42 has a rectangular hollow portion 43 into which is telescoped a rectangular intermediate member 44, and a rectangular button 45 is telescoped into the member 44. A clip 47 of substantially the same design as the clip 15 of FIG. 1 to 6 can be used for receiving one end of a spring (not shown). Besides being rectangular or circular, the various elements also can be square, polygonal or of any other suitable shape.

Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.
